Beschreibung
Zusammenfassung:	A container-closure assembly. The container has a discharge opening, a locking flange of generally circular opening with a frusto conical side face diverging downwardly from the axial end face of the opening. A shaping surface is formed below the locking flange of non-circular cross section and has a maximum cross section less than the cross section of the locking flange and at least one cam member extends axially downwardly from the locking flange. The cap of the assembly has a top and a peripheral skirt portion engaging under the locking flange and extending at least to the juncture of the locking flange and shaping surface. The cap is of a deformable material whereby the skirt is shaped to a generally circular shape by the cam member upon relative rotation of the cap and container.
